Function formatQualifiers

pkg/search/query.go:291–331

formatQualifiers renders qualifiers into a plain query. The formatter is a custom formatting function that can be used to modify the output of each qualifier. If the formatter returns (nil, false) the default formatting will be applied.

(qs Qualifiers, formatter func(qualifier string, vs []string) (s []string, applicable bool))

// output of each qualifier. If the formatter returns (nil, false) the default
// formatting will be applied.
func formatQualifiers(qs Qualifiers, formatter func(qualifier string, vs []string) (s []string, applicable bool)) []string {
	type entry struct {
		key    string
		values []string
	}

	var all []entry
	for k, vs := range qs.Map() {
		if len(vs) == 0 {
			continue
		}

		e := entry{key: k}

		if formatter != nil {
			if s, applicable := formatter(k, vs); applicable {
				e.values = s
				all = append(all, e)
				continue
			}
		}

		for _, v := range vs {
			e.values = append(e.values, fmt.Sprintf("%s:%s", k, quote(v)))
		}
		if len(e.values) > 1 {
			slices.Sort(e.values)
		}
		all = append(all, e)
	}

	slices.SortFunc(all, func(a, b entry) int {
		return strings.Compare(a.key, b.key)
	})

	result := make([]string, 0, len(all))
	for _, e := range all {
		result = append(result, e.values...)
	}
	return result
